Poor Customer Service and Worst Escalation Process

Please an order in 22/10/2021, payment completed after almost a year after being send from pillar to post. Called the ISP numerous times and all they can say its escalated to Vumatel. This is the worse service I have received and as patient as I have been I am considering cancelling the order, and on the hindsight they failed to address order, how will they refund me? No contact centre to call but through MWEB this is just frustrating. My last reference number: MWB***7 and ISP-843442
